The Isothermal Transformation of Low-Alloy Low-C CMnSi Steels below M_S

Abstract:

An isothermal transformation was observed when a low-alloy, low-carbon steel was quenched and held in the MS–Mf temperature range after austenitized above A3. The precise nature of this isothermal transformation is still unclear. The present contribution is a comprehensive comparison using EBSD, internal friction (IF) and TEM analysis of the isothermal transformation product, the athermal martensite and the lower bainite. The observations revealed that the isothermal transformation product in the MS-Mf temperature range had its own microstructural characteristics with wavy lath boundaries and orientation relationship.
